Fastest way to activate the pineal gland is sleep deprivation, preventing the pineal gland to secrete dream hormones, building them up, and resulting in the pineal gland restoring itself. Too much sleep is what made the pineal gland's hormone secretion unbalanced in the first place. So the fastest way to restore balance is sleep deprivation. It is a similar process like fastening to heal your stomache. If an organ does not have any rest, how can it restore itself?

For me 3 days did the trick. It is not easy, and what you need is excitement, but I see you already have that. I really don't understand why people tell you to relax as relaxing is going to make you fall asleep unconsciously. Why do so many people fail at WILD? It is because they relax, lose focus and fall asleep. WILDing is the hardest thing ever, if you managed to WILD 4 times in three weeks, then that pretty much makes you an expert on the subject. Be very careful with other people their advice as they do not always know what they are talking about and their advice may lead you to lose progress instead.
